BUILDING FORM.

Application filed .Tune 21,

My present invention'has reference to a building construction in which stone orconcrete slabs are employed, thesaid slabs being arranged in courses and having their edges provided \'vi.'th confronting grooves, while means of a' novel nature is employed tor holding the inner and outer slabs in` spaced relation, for insertingv a concrete between the ljoints thereof and ior producing a building having a dead air space between the walls thereof.

A still further vobject is to simplify and improve the building Const-ri 4 'on upon which have received U. S. Let` rs Patent No. 1,451,144, granted April 10, 1923, in a manner whereby substantially' halt of the material employed in' the patented construction is utilizedwitli' the improvement.

To the attainment'of the foregoing and other objects which will present themselves as the nature of the .invention is better uuderstood, reterence is to be had tothe drawings which accompany and which torm part of this application.

Figure 3 is a plan view of the corner ot' the building.

Figure 4 is an enlarged sectional view approximately on the line 4+4 of Figure 1.

Figure 5 is a similar sectional; view approximately on the line 5 5 of Figure 4.

Figure 6 is' an enlarged fragmentary sectional View on the line 6 6 ot Figure 1.

Figure 7 is a perspective view of the outer corner plate.

Figure 8 is a similar view of the horizontal corner plate.

Figure 9 is a similar View ot the inner corner plate.

Figure 11 is a similar view of one ot the horizontal plates which connect the vertical wall plates.

Figure 12 is a. similar view of the longitudinal spacer plate.

1n carrying out my present inventioiul employ parts substantially similar' to those abl pla 1924-. semi No. 721,542.

disclosed in my Patent No.y 1,451,144 and therefore will not set forth in vdetail the construction ot such parts more than is nec` essary to clearly set t'orth my present improvement.

As shown in the drawings the building construction includes inner and outersuperimposed courses ot slabs which have their edges longitudinally grooved and if necestheir end may be likewise grooved. The wall construction is laid onl a concretev foundation 1 and embedded in the upper "ace or" the said toundati'on there are metal as or plates having inturned ends to re- ELudinal grooves ot' the lower ,1 nl outer slabs 2. This connot been illustrated, as the 1 been clearly set forth in my rered to patent. rihe upturned vends o1' the ceiye therebetween the inner vertical rilhe wall plates 3, as well as e r ard outer corner plates 4 and 5 e constrpction set forth in my patent, being here deemed only necessary to say that the same' have their bottoms flanged, notched and slitted their upper edges ined with projecting tongues Aand with 1lb-e substantially U-shaped wall Fates 3 are of a length equalling the width i r the slabs 2, and as disclosed by the drawings are disposed alternately at the opposite sides of the wall.

l1`he't'ongues 6 and 7 on the top of the wall of' theV alternately arranged vertical wall plates 3 are d'esignedto be passed through angula'rl -,`fy arranged slots Sra-nd 9-'-9 on the horizontal' tie plates 11, while the hanged b ase 12 of the vertical wall plates 3 are designed to have their slots 13 received between right angularly arranged upstanding flanges 14 on the said horizontal tie plates 11.

Each of the tie plates 11 has its body inclined inwardly from its ends to its center and its inclined edges are flanged, as at 14. rllhe straight outer edges of the said plates are also flanged, as at 15, in the direction of the anges 9. The body of the plates adjacent the said flanged ends 15 are slitted at spaced intervals and the metal bounded by the slits is rounded upwardly to provide ianges 16 disposed opposite the flanges 15. and shorter angle flanges 17 at the sides of the flanges 16. Each of the plates 11, at the side thereof provided with the slots 8 and 9 is formed with an opening 18, the purpose ot which will presently be apparent. rEhe flanges 15 and 16 are received in the grooves of the confronting courses of slabs 2, the flanges 17 spacing the said courses, so that mortar poured through the -openings 18 at the alteinate sides of the horizontal layer of plates 11 will seep into the horizontal joints of the slabs. The base 12 of the vertical plates 3 are really in the nature of flanges, and therefore will not retard the downward flow of mortar. To provide for this, as well as to provide a spacing means for the substantially U-shaped plates 11 produce angle plates, illustrated in Figure 12. rThe hoiizontal flange 19 of the spacer plate is centrally slitted both vertically and longitudinally and the metal bounded by the slits is bent angularly in the same direction to provide spaced arms 20. rhese arms have inturned ends 21. The inturned portions or arms 2O are designed to straddle the substantially U-shaped vertical wall plates 3, the flanges thereof engagingv the edges of the flanged sides of the said plates. The horizontal element of the spacer plate is indicated by the numeral 22, and has its edges bent to form ways 23 for a plate 24 illustrated in Figure 13. The plate 2i is slid through its ways until the same contacts with the inner faces of the wall structure. The ends of the vertical element of the wall plate are slitted vertically to provide upper tongues 25 and lower tongues 26, the upper tongues 25 designed to be received through slots or notches 27 at the juncture ofthe flanges with the body of the vertical plates at the ends thereof as well as in central notches 28 in the plates 11. The horizontal corner plates are substantially similar to those set forth in my patent and engage the outer and inner vertical plates i and 5 in substantially the same manner. The horizontal corner plates 29, however, are preferably forined from a single sheet of metal and have their edges bent to form oppositely eX- tending flanges on their outer corners and spacer flanges 30 between the lower spaced flanges to be received between and to space the joints at the corner of the construction so that mortar will flow into said joints.

in my present construction it will be noted :iff

that mortar is alternately poured from both of the inner sides of the building construction in the course of the erection thereof, and that substantially one-half of the metal and mortar used in my patented construction is employed in the improvement. The improvement, it may be stated, is primarily directed to small buildings and bungalows.

lVhile is believed that the foregoing description, when taken in connection with the drawings will fully set forth the details of my construction and the advantages thereof, it is to be understood that l am not to be restricted to the precise structural details disclosed, but am entitled to all such changes therefrom as fairly fall within the scope of what l claim.

Having described the invention, I claim fr hollow wall construction comprising two spaced courses of slabs which are arranged in staggered relationship in the same course and also with relation to the other course,

said slabs having grooves extending across their two horizontal suiiaces, tie plates having flanges received in said horizontal grooves, horizontally arranged spacer plates of a length equal to the length of a slab supported by said tie plates, said spacer plates consisting of horizontal elements, the ends of which receive the tie plates, and vertical elements in right angular relationship, said vertical elements being slitted centrally and having spaced arms with inturned ends which straddle lei-shaped vertical wall plates of the height of a slab and a filling of mortar in the voids formed by said spacer plates and said wall plates.

In testimony whereof I affix my signature.

FRANK L. DECKER.
